Six point charges are kept $$60^{o}$$ apart from each other on the circumference of a
circle of radius $$R$$ as shown in figure . The net electric field at the center of the circle is______.
( $$\epsilon_{o}$$ is permittivity of free space)

A

$$-\frac{Q}{4\pi\epsilon_{o}R^{2}}\left(\sqrt{3}\widehat{i}- \widehat{j} \right)$$

B

$$-\frac{5Q}{8\pi\epsilon_{o}R^{2}}\left(\widehat{i}+ \sqrt{3}\widehat{j} \right)$$

C

$$-\left(\frac{5Q}{8\pi\epsilon_{o}R^{2}}\right)\left(\widehat{i}- \sqrt{3}\widehat{j} \right)$$

D

$$\frac{Q}{4\pi\epsilon_{o}R^{2}}\left(\sqrt{3}\widehat{i}- \widehat{j} \right)$$
